Disk ZFS logical IO operations

Disk: ZFS logical I/O operations

This statistic shows logical access to the ZFS file system as operations/sec.
Logical I/O refers to the type of operations as those that
are requested to the file system, such as by NFS; as opposed
to physical I/O, which are the requests by the file system to
the back-end pool disks.

When to check

This could be useful while investigating how I/O is processed between the
Protocol layer and pool disks.
